A reactive-separation process converts glycerin into lower alcs., having b.ps. of less than 200 degrees, at high yields. Conversion of natural glycerin to propylene glycol through an acetol intermediate is achieved at 150-250 degrees at a pressure 1-25 bar. The preferred applications of the propylene glycol are as an antifreeze, deicing compound, or anti-icing compound. The preferred catalyst for this process is a Cu-Cr powder.
